Types ¶
type Backend ¶
type Backend struct {
// contains filtered or unexported fields
}
Backend is a simulated blockchain. You can use it to test your contracts or other code that interacts with the Ethereum chain.
func New ¶
func New(alloc core.GenesisAlloc, gasLimit uint64) *Backend
New creates a new binding backend using a simulated blockchain for testing purposes. A simulated backend always uses chainID 1337.
func (*Backend) AdjustTime ¶
AdjustTime changes the block timestamp and creates a new block. It can only be called on empty blocks.
func (*Backend) Close ¶
Close shuts down the simBackend. The simulated backend can't be used afterwards.
func (*Backend) Fork ¶
Fork creates a side-chain that can be used to simulate reorgs.
This function should be called with the ancestor block where the new side chain should be started. Transactions (old and new) can then be applied on top and Commit-ed.
Note, the side-chain will only become canonical (and trigger the events) when it becomes longer. Until then CallContract will still operate on the current canonical chain.
There is a % chance that the side chain becomes canonical at the same length to simulate live network behavior.
type Client ¶
type Client interface {
ethereum.BlockNumberReader
ethereum.ChainReader
ethereum.ChainStateReader
ethereum.ContractCaller
ethereum.GasEstimator
ethereum.GasPricer
ethereum.GasPricer1559
ethereum.FeeHistoryReader
ethereum.LogFilterer
ethereum.PendingStateReader
ethereum.PendingContractCaller
ethereum.TransactionReader
ethereum.TransactionSender
ethereum.ChainIDReader
}
Client exposes the methods provided by the Ethereum RPC client.
